Get a specific recurring value from JSON array using PHP foreach loop -

i have following json array:

{"key1":"example1","key2":"example2","key3":"example3","key4":"example4","key1":"example5","key2":"example6","key3":"example7","key4":"example8","key1":"example9","key2":"example10","key3":"example11","key4":"example12"} 

using php possible display specific recurring value, example if wanted display "key1" in foreach loop return following:

example1 example5 example9 

appreciate tips on use this, thanks.

you aren't going able using json_encode because it's not valid json. (keyspace collision)

you going need assemble object manually.

you might consider creating individual items, using implode(). can prepend , append { , }.

<?php $jsonobject='{"key1":"example1","key2":"example2","key3":"example3","key4":"example4","key1":"example5","key2":"example6","key3":"example7","key4":"example8","key1":"example9","key2":"example10","key3":"example11","key4":"example12"}';  $jsonarray = array_map(     function($array){     $keyvalue=explode(":",$array);     return array("key"=>substr($keyvalue[0],1,-1),"value"=>substr($keyvalue[1],1,-1));      },     explode(         ",",         substr($jsonobject,1,-1)      ) );  foreach($jsonarray $object){     $output[$object['key']][]=$object['value'];  } echo implode("\n",$output['key1']);  ?>
